How do you use the discriminant to find out how many real number roots a2+12a+36=0 has?Use of the Discriminant:The discriminant of a quadratic equation is used to determine the number and the nature of the roots. The discriminant is denoted by the alphabet ...
What is a discriminant formula? Discriminant, in mathematics, a parameter of an object or system calculated as an aid to its classification or solution. In the case of a quadratic equation ax2+ bx + c = 0, the discriminant is b2− 4ac; for a cubic equation x3+ ax2+ bx + c = 0...

Knowing how to find the vertex of a parabola enables us to write the equation of a parabola given only limited information about it. What is the vertex of a quadratic function? The vertex of a quadratic function is the vertex of the graph of that function. Given a quadratic function in ...
If a quadratic polynomial is equated to zero it becomes a quadratic equation. The values of \(x\) satisfying the equation are known as the roots of the quadratic equation. What is Discriminant? The value of \(\left( {{b^2} – 4ac} \right)\) in the quadratic equation \(a{x^2} ...

To establish if we have obtained a reliable factor solution, we look closely at indicator reliability, scale reliability, construct validity, and discriminant validity (Brown2015). As a measure of indicator reliability, we look at squared factor loadings, which indicate how much of the variance in...
